FOSTER CITY, CA — May 25, 2010 —Equinix, Inc. (Nasdaq: EQIX), a provider of global data center services, today announced that Zetta, a provider of on-demand enterprise storage solutions, is using Equinix's Silicon Valley International Business Exchange (IBX) data center to ensure secure, uninterrupted service to its customers. Zetta chose Equinix to support the successful launch of its on-demand enterprise storage solutions in 2009 based on Equinix's ability to deliver reliable service, network-neutral connectivity and the opportunity for cost-effective expansion.

As an early-stage company in the storage services industry, reliability and network connectivity were crucial elements in Zetta's decision to choose a data center provider. The company needed a data center partner that could deliver these critical features, as well as state-of-the-art facilities, high availability, robust security and network neutrality. The need to support these areas, coupled with aggressive SLA requirements, led Zetta to select Equinix.

“We told our team to find the best data center provider, and Equinix emerged as the partner that was most capable of supporting our needs. Equinix makes it possible to find economical choices for network connectivity, which helps us contain costs,” said Jeff Whitehead, CTO, Zetta. “At the same time, many of our customers are also in Equinix facilities, so see added benefits with extremely low latency and high-capacity connection at low cost. We were confident that Equinix would be the right data center partner, and given the reliability before, during and after the successful launch of our storage services, that decision has certainly been validated.”

Working with Equinix will also enable Zetta to cost-effectively execute on its aggressive expansion plans by providing a single supplier with consistent policies and procedures for facilities across the US. Zetta has already doubled the number of racks in the Silicon Valley IBX since the launch in 2009 and expanded its primary storage facilities to the East Coast with Equinix in 2010. Equinix simplifies the process of deploying into new data centers across the country.

“The combination of interconnection, reliability and network neutrality means that we provide unique value to the many service providers that rely on Equinix,” said Vince DiMemmo, General Manager, Global Cloud Computing at Equinix. “Zetta is at the cutting edge of on-demand storage, and we are thrilled to support them as they continue to innovate and grow.”
